Most coordinate conversion tasks are easy to perform with FME. Wherever automated translations are possible, reprojections are as simple as choosing different source and destination coordinate systems. The FME features are coordinate system aware and reproject themselves appropriately.
However, when coordinate data is held in attribute values, this process cannot be completely automated. Tabular data stored in ASCII files cannot be translated automatically. In this case, you must use the AttributeReprojector transformer to accomplish this task.
Insert the transformer and connect it to your input dataset.
Select the X and Y coordinate values.
Select the Source and Destination Coordinate systems.
NOTE: Make sure you have not also specifed source and destination coordinate systems through the Navigator pane in Workbench.
